摘要：This invention relates to a polyamide-imide precursor, a polyamide-imideobtained by imidizing the same, a polyamide-imide film, and an image display deviceincluding the film. The polyamide-imide precursor includes, in a molecular structurethereof, a first block, obtained by copolymerizing monomers including dianhydride anddiamine, and a second block, obtained by copolymerizing monomers including anaromatic dicarbonyl compound and aromatic diamine. The dianhydride includesbiphenyltetracarboxylic acid dianhydride (BPDA) and 2-bis(3,4-dicarboxyphenyl)hexafluoropropane dianhydride (6FDA), and the diamine includesbistrifluoromethylbenzidine (TFDB).
